Description

Technical Field

[0001] The utility model relates to a fan installation structure, in particular to an outdoor heat dissipation fan installation structure of a photovoltaic inverter. Background Art

[0002] Fans are used as cooling tools in many fields. For example, fans are set on photovoltaic inverters. Photovoltaic inverters will generate heat during operation, and fans can accelerate air flow and help dissipate heat, thereby ensuring that the temperature of the photovoltaic inverter is within the normal working range.

[0003] The fan usually includes a fixing plate, a fan blade assembly and a protective mesh cover. There are currently two types of fans on the market. One type of fan has a fixing plate and a protective mesh cover that are separated. That is, after the fan blade assembly is installed, the protective mesh cover still needs to be installed. This requires the processor to perform multiple assembly tasks, which increases the complexity of the processing, thereby increasing the difficulty of the assembly process and increasing the cost.

[0004] The other is a fixing device in which the fixing plate and the protective mesh cover are integrally formed. The fan blade assembly only needs to be installed on one side of the fixing device so that the positions of the protective mesh cover on the fixing device and the fan blade assembly correspond. However, although the fans with this installation structure currently on the market reduce the difficulty of assembly, there is a problem of a small distance between the fan blade assembly and the protective mesh cover, which leads to greater wind resistance and noise, thereby affecting the service life and working efficiency of the fan. Utility Model Content

[0005] In order to solve the problems in the related art, the present application provides an outdoor cooling fan installation structure for a photovoltaic inverter, which solves the problems of large wind resistance, high noise, short service life and low working efficiency.

[0006] The technical solution is as follows:

[0007] A photovoltaic inverter outdoor cooling fan mounting structure comprises a fixing plate and a fan blade assembly detachably mounted on one side of the fixing plate, wherein the fixing plate corresponding to the fan blade assembly is provided with a through hole, and the fixing plate is characterized in that a protective net integrally formed with the fixing plate is provided on the fixing plate along the periphery of the through hole, and the side of the protective net away from the fixing plate is convex outward.

[0008] Through the above technical solution, by making the protective net protrude outward, the distance between the fan blade assembly and the fixing plate can be increased, thereby reducing wind resistance and wind noise, thereby improving the service life and working efficiency of the fan;

[0009] By providing an integrally formed protective net on the fixed plate, the step of installing the protective net can be omitted, thereby reducing the complexity of installation and further reducing the processing technology requirements; and directly integrally forming the protective net on the fixed plate can reduce the amount of material used, thereby reducing production costs and increasing the stability of the device.

[0010] Preferably, a mounting plate is provided on the side of the fixed plate away from the protective net, and a accommodating cavity for accommodating the fan blade assembly is provided on the mounting plate. The accommodating cavity corresponds to the position of the protective net, and the accommodating cavity runs through the two side surfaces of the fixed plate parallel to the fixed plate.

[0011] Preferably, the accommodating cavity is provided with an integrally formed fixing ring and a plurality of fixing rods arranged along the outer periphery of the fixing ring, the other end of each fixing rod is fixedly arranged on the inner wall surface of the accommodating cavity, a fixing rod among the plurality of fixing rods close to the bottom of the fixing plate is provided with a strip groove, the strip groove is arranged along the length direction of the fixing rod, one end of the strip groove extends to the bottom of the mounting plate; a rotating shaft matched with the fixing ring is arranged along the inner wall of the fixing ring, the other end of the strip groove extends into the rotating shaft, and the fan blade assembly is sleeved on the rotating shaft.

[0012] Through the above technical solution, through the setting of the strip groove, the wires used to connect to the external power supply can be arranged in the strip groove, which is conducive to the storage of the wires and can save installation space, thereby facilitating subsequent maintenance.

[0013] Preferably, the fixing plate is provided with a plurality of first mounting holes, and the first mounting holes are through holes, and second mounting holes are provided at corresponding positions on the mounting plate, and bolts are provided in the first mounting holes, and the other end of the bolts passes through the second mounting holes, so that the mounting plate is installed on the side end surface of the fixing plate.

[0014] Preferably, each of the four corners of the mounting plate is provided with notches.

[0015] Through the above technical solution, by setting the notch, the weight of the mounting plate can be reduced, thereby ensuring the stability of the device after installation.

[0016] In summary, the beneficial effects of an outdoor cooling fan installation structure for a photovoltaic inverter are:

[0017] 1. By making the protective net protrude outward, the distance between the fan blade assembly and the fixed plate can be increased, thereby reducing wind resistance and wind noise, thereby improving the service life and working efficiency of the fan; by setting an integrally formed protective net on the fixed plate, the step of installing the protective net can be omitted, thereby reducing the complexity of installation and the processing requirements; in addition, the protective net directly integrally formed on the fixed plate can reduce the amount of materials used, thereby reducing production costs, and can also increase the stability of the device;

[0018] 2. Through the setting of the strip groove, the wires used to connect the external power supply can be arranged in the strip groove, which is conducive to the storage of the wires and can save installation space, thereby facilitating subsequent maintenance.
